While working underground, miners are exposed to a number of risk factors that have a negative impact on their health and may be a cause of an increased mortality in miners. The aim of the study was to compare total and specific mortality in black coal miners with acknowledged coal-workers' pneumoconiosis (CWP) and without CWP, and the mortality of the general male population in the Czech Republic in the period 1992-2013. The sample consisted of 3476 coal miners with CWP and 6687 ex-coal miners without CWP, who were removed after achieving the maximum permissible exposure (MPE)...

Objective: To guide the rational use of antibiotic drugs in clinical practice for doctors by the analysis of pathogens distribution, transition and drug resistance of bacteria in sputum samples of pneumoconiosis patients combined with lower respiratory tract infection. Methods: 2 199 qualified sputum samples from 214 pneumoconiosis patients collected from January 2008 to December 2012 were examined by bacterium or fungus education. BioMerieux API and Eastern Cowin application software were used to do bacterial identification, and K-B method recommended by the NCCLS was used to take drug sensitivity tests...

Objective: To investigate the value of means of surfaces with nonhomogeneity (MSN) in esti-mating the incidence of pneumoconiosis. Methods: Based on the principal component analysis, all counties (districts) of Hebei Province, China, were divided into three categories according to the degree of pneumoconiosis hazards and the MSN model was used to estimate the incidence rate of pneumoconiosis and the number of pneu-moconiosis cases using the data of the incidence of pneumoconiosis in 2010. Results: With reference to the appli-cation requirements of the MSN model, results of the principal component analysis, and expert experience, the 172 counties (districts) in Hebei Province were divided into three categories with mild, moderate, and severe pneumoconiosis hazards...

Objective: Investigate the pulmonary surfactant autotransfusion effect on the recovery of respiratory function in patients with whole lung lavage, to provide theoretical basis for the clinical application. Methods: We taken 30 patients of pneumoconiosis treated by whole lung lavage as the subjects. We extracted the pulmonary surfactant from lavage fluid, after single postoperative lung lavage for the first time; after one weeks when the second times of lung lavage were performed to the other side of the lung of patients, we put PS into the right side...

A 60-year-old man presented with an 18-month history of gradually worsening cough and a 12-month history of dyspnea on exertion. High-resolution computed tomography showed bilateral uniform ground grass opacity in the lower lung fields, partially resolved by smoking cessation. A tentative diagnosis of desquamative interstitial pneumonia (DIP) was made. Video-assisted thoracic surgery was performed and pathological analysis showed peribronchiolar fibrosis with intra-alveolar macrophage infiltration. Elemental analysis detected aluminum and iron in the upper lobe and only iron in the lower lobe...

BACKGROUND: Brachial-ankle pulse wave velocity (baPWV) is an independent predictor of cardiovascular events and mortality. However, there is no related data on the association of baPWVwith coal workers' pneumoconiosis (CWP). We explored the baPWV in subjects withCWP and the associated risk factors. METHODS: Thiscase-control study included 1,007 male CWP cases without a history of stroke and coronary heart disease and 1,007 matched controls from the Kailuan cohort study...

BACKGROUND: Transforming growth factor-beta 1 (TGF-β1) and gene variants have been extensively studied in various human diseases. For example, TGF-β1 polymorphisms were associated with fibrosis and pneumoconiosis, but the data remained controversial. The aim of this meta-analysis was to assess the association between TGF-β1 -509 C>T [rs1800469], +869 T>C [rs1800470], and +915 G>C [rs1800471] polymorphisms and pneumoconiosis. METHODS: A comprehensive literature search was conducted through searching in PubMed, Embase, the Chinese Biomedical Database, and the Wei Pu (Chinese) Database by the end of April 2016...

It is difficult for radiologists to classify pneumoconiosis from category 0 to category 3 on chest radiographs. Therefore, we have developed a computer-aided diagnosis (CAD) system based on a three-stage artificial neural network (ANN) method for classification based on four texture features. The image database consists of 36 chest radiographs classified as category 0 to category 3. Regions of interest (ROIs) with a matrix size of 32 × 32 were selected from chest radiographs. We obtained a gray-level histogram, histogram of gray-level difference, gray-level run-length matrix (GLRLM) feature image, and gray-level co-occurrence matrix (GLCOM) feature image in each ROI...

Objective: Using spatial autocorrelation analysis to study spatial distribution characteristics of pneumoconiosis in China. Methods: The incidence of pneumoconiosis of each province from 2009 to 2013 was calculated by reported data of pneumoconiosis and the number of employment in mining and manufacturing of each province from Chinese statistical yearbook. The global and local spatial autocorrelation analysis was im-plemented by global and local's Moran's I index respectively. Results: A total of 112 066 new cases of pneumo-coniosis were reported from 2009 to 2013 in China, Global Moran's I from 2009 to 2013 was -0...

OBJECTIVE: The Japanese government established the Pneumoconiosis Law in 1960 to protect health and promote the welfare of workers engaged in dust-exposed works. This article describes Japanese practice in workplace health management as regulated by the Pneumoconiosis Law to reduce pneumoconiosis in Japan. METHODS: We collected information addressing pneumoconiosis and the health care of dust-exposed workers. We included all types of scientific papers found through a PubMed search as well as official reports, guidelines, and relevant laws published by the Ministry of Health, Labour and Welfare (MHLW) of Japan and other academic institutions...

Coal workers' pneumoconiosis, also known as "black lung disease," is an occupational lung disease caused by overexposure to respirable coal mine dust. Inhaled dust leads to inflammation and fibrosis in the lungs, and coal workers' pneumoconiosis can be a debilitating disease. The Federal Coal Mine Health and Safety Act of 1969 (Coal Act),* amended in 1977, established dust limits for U.S. coal mines and created the National Institute for Occupational Safety and Health (NIOSH)-administered Coal Workers' Health Surveillance Program with the goal of reducing the incidence of coal workers' pneumoconiosis and eliminating its most severe form, progressive massive fibrosis (PMF),(†) which can be lethal...

BACKGROUND Accumulating evidence shows that functional impairment in subjects with coal workers' pneumoconiosis (CWP) is principally due to emphysema and airflow obstruction, rather than underlying restrictive mechanisms. However, cigarette smoking has remained a major confounder. The aim of this study was to assess whether coal dust exposure was associated with emphysema and/or airflow obstruction in the absence of smoking history. MATERIAL AND METHODS The subjects evaluated for possible pneumoconiosis between 2013 and 2015 were retrospectively enrolled into this study...

During the last 1.5 years an update of the guideline on silicosis was made by an interdisciplinary working group. New medical and scientific knowledge and the experience in expert opinion practice were taken into account.By preparing the initial guideline in 2010 standardization of diagnostics and adaption of the "Moers convention" which was not based on medical knowledge was in the focus, whereas the current update deals with fine emendation and extension, especially of the compensation rate (adaption with the Reichenhall recommendation)...

OBJECTIVES: To construct a phage display human antibody library (PDHAL) against pneumoconiosis for the diagnosis and treatment of coal worker pneumoconiosis (CWP). METHODS: The PDHAL was established via CWP blood and six positive antibodies were discovered. 867 coal workers (558 CWP and 309 without CWP) and 393 controls were recruited to validate the results. RESULTS: A PDHAL against CWP was established, from which six strong positive clones were selected, sequenced and identified as VEGF, interleukin-18, HSP70, HER3, Gz-B and RF...
